Where is the Toyota Corolla sensor?

Sensors have different functions and positions. The sensor position of Toyota Corolla is as follows: 1. Oxygen sensor: installed on the exhaust pipe, it is used to monitor the burnt gas and judge whether the engine is fully burned and whether the mixing degree is too thin or too rich. 2. Wheel speed sensor: generally located on the front wheel brake disc, it is used to collect the vehicle speed to judge whether it slips, and installed on the hub of each wheel. If the sensor is damaged, ABS will fail. 3. Water temperature sensor: installed beside the thermostat, it converts the temperature of cooling water into an electrical signal, increases the fuel injection amount or ignition advance angle at low temperature, prevents explosion at high temperature, and delays the ignition advance angle. 4. Intake pressure sensor: generally installed on the throttle valve, it senses a series of resistance and pressure changes with different engine speed and load, and converts them into voltage signals for ECU to correct fuel injection quantity and ignition timing angle. If it fails, it will cause problems such as difficult ignition, unstable idle speed and weak acceleration. Therefore, the functions of sensors are different, and the positions are not necessarily similar.
